INVENTOR WITNESSES ATTORNEY ROBERT s. B RC orv CARI/IONA, TEXAS.

GI-IIMNEY-CQWL.

To all whom it may concern:

Be it known that 1, ROBERT S. BURCH, a citizen of the United States, residing at Carmona, in the county of Polk and State of Texas, have invented certain: new and useful Improvements in Chimney-Cowls, of which the following is a specification.

The present invention has relation to certain new and useful improvements in chimneycowls and as its primary object it contemplates the provision of a novel device of this nature that is of a construction whereby it may be easily and quickly associated with the respective chimneyv or Smokestack and which, when in place will insure a proper draft at all times and collect the sparks so as to prevent the same from falling on and igniting the roof or other combustible object.

A further object of my invention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly practical from both the standpoint of the manufacturer and the standpoint of the user; and which, it is belleved, may be manufactured at a comparatively low cost. 1 i

.These objects are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification and then more specifically pointed out in the appended claims. 1

.In the accompanying drawings wherein like characters designate like parts throughout the several'views:

of upstanding supporting arms 11, as at 12,

the said supportmg arms in turn carrying,

venting the entrance of rain or other eX-i traneous matter. This bonnet or hoodmay be constructed of any desiredmateriahhowever it is pointed out that alight metal is preferable.

A suitable curved support or yoke 14: is mountedto be revoluble with respect to the hood or bonnet13 through the instrumentality of a stud 15, one end thereof projecting below the lower edge of the hood or bonnet and designed to carry a semi-cylindrical guard plate 16-, secured thereto by .means such as shown. at 17. This guard plate is to be of a width substantially the same as the-distance between the upper edge of the body member 10 and the lower edge of the hood; or bonnet whereby it will'alford an adequate shield which, as is obvious, is

readily movable to different positions about -85 end of the yoke 14 is extended downwardly,

the vertical center of device. The other as shown inFig. 1, to form a back or securing portion 18 and an angularly-extending supporting portion 19. A substantially semi-circular basket 20 that may be formed of any recticular or interstitial'material may now be associatedwith the arm 14 in the manner shown in-Fig. 1, a portion thereof being connected to the ortion 18 of the yoke as shown at 21 wh1le the portion 19 of the yoke extends beneath the basketand may be connected thereto as at 22. Consequently it will be recognized that the basket will be held securely in position at all times, while the portion 19 of the yoke forms an adequate support for the bottom of the basket to relieve the strain thereon when foreign materialhas accumulatedtherein; v

As is obvious upon reference to'Fig'Q, the basket 20 is diametrically opposed to the guard plate 16 and movable 'togetherth'er'ewith,"where'by the smoke passing upwardly from the stack or pipe A will pass outwardly through the basket: the usual manner, :while th guard plate is oficonns'ev shiftedqat 119' certain times, as will hereinafter appear, in accordance wlth the valuation ofihe a1r current.

. I further provide a vane 23 that may be fixed to the yoke 1a through the instrumentality of a member 24 and fastening members25 thus providing for the proper .ad

"j'ustment of the guard plate '16 and the basket in accordance with the variation of the air current, as stated above.

The supporting members 11, belng placed on the inner periphery of the body member air'current, acting on the vane 23, will of course shift the vane to variou positions which will in turn cause the actuation of the guard plate 16 and the basket 20 as above referred to. The smoke passing through the basket 20 will be relieved of sparks and other foreign matter, the latter falling onto the bottom of the basket. Both the guard plate 16 and the basket 20 are readily rotatable with respect to the chimney by reason of the efficient support of the carrying arm let and by reason of this construction it will be noted that the device is not likely to get out of order.

From the foregoing it is believed that the advantages and novel features of my invention Will be readily understood and therefore further detail description is deemed unnecessary.

Tn reducing my invention to practice I find that the form referred to herein as the most practical and preferred embodiment is the most efficient, but realizing that certain conditions will necessarily vary in concurrence with the adoption of my device, I desue to emphasize the fact that various minor change in the details of construction and in the proportion of parts may be resorted to when required without sacrificing any of the dvantages of my invention as defined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A-chimney cowl comprising a hollow body," an impervious hood extending over thehollow of said body and being spaced thereabove, and supported'by said body, a support pivotally mounted on said hood and extending from side to side of the latter, a wind shield supported by one end of said support and substantially closing one side of the space between said body and hood, a reticular element supported by the other end of said support and disposed diametrically opposite to said wind shield and covering a portion of the space between said body and said hood, and means operable by the wind for turning said support I on its. pivot.

52. In a chimney cowl, supporting means associated with the chlmney or stack, arms carried thereby, a hood carried by sald arms, a carrying memberrotatably mounted 'whereby the guard plate and said basket may be moved in consistence with the variation of the air current, as and for the purpose specified.

3. A chimney cowl consisting of a hollow body attachable to a chimney, a hood extending over said hollow body, a plurality of arms each having one end within said hollow body and secured thereto and have its other end within said hood and secured thereto so as to support the hood in spaced relation above said hollow body, a yoke piv- V otally mounted on said hood, a windshield carried by one end of said yoke, and substantially covering one side of the aperture between said hollow body and hood, a reticular spark-arresting element separated by the other end of said yoke andsubstantially covering the opposite side of said space, and a vane carried by said yoke and operable by the wind'for rotating the yoke and wind shield and reticular element exteriorly of the said arms. r 4. Tn a chimney cowl, a body member adapted to be associated with the chimney or stack, a bonnet arranged above said body member in spaced relation, means carried by said body member to support said bonnet, a carrying arm revolubly mounted with respect tosaid bonnet, and supported thereby, a guard member carrie d by one end of said arm'and interposed between said bonnet and said body memberand movable with respect to'said body member and said bonnet, a basket formed of reticulated material and carried by the other end of said arm and arranged oppositely with respect to said guard plate, means carried by said arm to support the bottom of said basket, and a vane associated with said carrying arm, whereby said guard and said basket may be moved in consistence with the variation of the air current,as and for'the purpose speci- Y 5.
